Hello, thank you in advance for whatever help you can give me. I purchased the AT&T galaxy s4 and I am trying to use it in Colombia with my provider Tigo which runs on 1900mhz but I have problems connecting to the internet.
This is my second galaxy s4, the first one I had I opened the AWS bands, selected WCDMA/GSM Mode Only on the service menu and my internet was working just fine. Unfortunately I lost my first phone and bought another one, and went through the same procedures but my mobile data is not working for the most part while it is connected to HSPAP.
If I select GSM only on the srvice menu then it navigates, but at 2G speeds. What seems strange is that I am getting great signal and when I go to about device/status, it shows it is connected to hspap, and gprs, but I dont have an internet connection except at a couple of places, for some reason when I am in my house it works (wifi off), but when I leave my house it doesnt work.
If you have had a similar problem an were able to figure it out I will appreciate any thoughts you may have. It is frustrating having this phone and not being able to use the internet.
Thank you.
I have a new SM-G935FD purchased in the UAE. The software version is MMB29K.G935FXXU1APD1. The phone has a "United Arab Emirates" section in the About page.
I travel a lot. I generally use a local SIM when I am in a country for some time. Right now I am in France. I am using a SIM from Bouygues Telecom but I have no 4G/LTE service at all. The phone is connecting at H+ and also at 3G, but it is not showing 4G/LTE at all.
I will be in several other European countries as well as the US soon. I specifically purchased this phone because it has all the LTE bands for the countries I spend time in. This same SIM does give me LTE connections on Bouygues when I use it in my old phone (a Motorola X 2nd Gen). I had expected this phone to just work on LTE everywhere that I typically go.
I have looked through these forums and see a thread or two about others with LTE problems. But no clear solutions.
I have tried various apps such as LTE Discovery (no luck) as well as 4G LTE Switcher - using that if I set "LTE only", I get no service at all, and then have to reboot the phone before I get service back.
Is there something I need to do to get LTE?
Thanks.
Have you put the SIM in the correct slot?

Yes, the bottom slot. The SDcard is in the top slot. The SIM is showing in the phone as "SIM1".
Strange. I have a G935FD and it works with LTE no problems. I've used it in Singapore and Indonesia, with different SIMs and all work.
In Settings - Mobile Networks - Network Mode, it's set to LTE/3G/2G?

Yes it is. I've tried changing to one of the non-LTE modes and back, but no change.
In the About device / Status / SIM Card status page, I see Mobile network type as UTMS. Shouldn't that have LTE and, if so, how do I change it?
Mine says the same, but I'm only connected to 3G at the moment, so I don't know if it's normal it not. I have a 4G card in, but I'm out of my area's 4G network range.
Edit: Actually I was connected to my wifi. Now I'm connected to my 3G and it says HSPA+ now
Edit again: Ok, so my phone is jumping between 3G and H+, which is what's changing.

Ah, mine is doing the same. I see Mobile network type jumping between UMTS and HSPA+ if I watch for a while. Obviously that field is a status field, not a setting field.
Thing is, I am in an area with full LTE coverage.
At least you seem to be confirming that this should work. Still need to figure out what the problem is.
I have the same Problem in Spain. With a Vodafone Card I dont have 4G Connection (The same card in a the Galaxy S5 of my wife works with 4G). But with a Yoigo Card I have 4G Connection. The software version is MMB29K.G935FXXU1BPH6. The phone has a "United Arab Emirates" section in the About page too. Any Idea?
Thanks

Have you tried to change nertwork mode to WCDMA only or GSM...or both WCDMA and GSM...????
Hi bro I am from Pakistan too so I research on it (couz I got 4g phone as well) I tried zong and didn't received signal so what I found is that these networks are on limited bands to work u need both phone and network to be same frequency supported to work 4g (and don't ask me how to do it couz I don't know either) try using warid (if possible) 4g it probably gonna work (not sure) or maybe you are not in 4g coverage area....

Help please
I also have this problem
Why is there no solution to the problem?
Hi guys,
Recently bought a used(6 months) OnePlus 2 - 2003...I was really satisfied with the performance and huge 4gig ram. I use only a single sim, which has 4G. I used the sim with a Nexus 5 until the phone die, but I have never had any signal issue with that phone. In y country not every area has 4G coverage. I currently have Oreo resurrection remix rom, latest build. In my home town 3G, 4G coverage is at it's best and even on 3G coverage I got decent amount of speed with Nexus 5.
The problem is OnePlus 2 doesn't give the slightest speed that H+ is capable even while I'm on 4G. speed is about 500kbps max with 4G. If I chose WCDMA Preferred, from the service menu, it does show H+, but I can't surf on the internet. I'm very disappointed with this phone now. If I were to go to an area with no 4G, It won't get data connection turned on no matter what I do. I even flashed latest OOS 3.6.1 firmware but no luck. I went back to OOS 3.6.1 and it's the same, cant' switch to 3G data.
Man I don't know what to do now, I don't get wifi all the time when I'm away from home. Is there any way to disable 4G and just use H+ or 3G?
I even changed the band in service menu (*#*#4636*#*#)
Also flashed the latest lineage 15.1, CM 13 and no matter what I do
I also tried couple of other sim/ISPs but no luck
Please Help me
Use Network Signal Guru app(root needed). In app, select LTE band lock and deselect your LTE bands(depend on your carrier) use for 4g and exit. It will prevent your phone from connecting to LTE band. Enable the band again to get the LTE.
